IS 269 : 2013 Hkkjrh; ekud lkèkkj.k iksVZySaM lhesaV] 33 xzsM — fof'kf"V ( ik¡poka iqujh{k.k ) Indian Standard ORDINARY PORTLAND CEMENT, 33 GRADE — SPECIFICATION ( Fifth Revision ) ICS 91.100.10 © BIS 2013 BUREAU OF INDIAN STANDARDS MANAK BHAVAN, 9 BAHADUR SHAH ZAFAR MARG NEW DELHI 110002 March 2013 Price Group 5 Cement and Concrete Sectional Committee, CED 2 FOREWORD This Indian Standard (Fifth Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by the Cement and Concrete Sectional Committee had been approved by the Civil Engineering Division Council. This standard was first published in 1951 and subsequently revised in 1958, 1967, 1976 and 1989. This revision incorporates the experience gained with the use of this standard and brings the standard in line with the latest developments in this field. Since the fourth revision of this standard, a large number of amendments were issued from time-to-time in order to modify various requirements based on experience gained with the use of the standard and the requirements of the users, and also keeping in view the raw materials available in the country and found suitable for the manufacture of cement. The important amendments included: use of performance improvers for addition during clinker grinding stage, incorporation of requirement of chloride content for the cement used in structures other than prestressed concrete, permitting use of 25 kg, 10 kg, 5 kg, 2 kg and 1 kg bags for packing of cement, and requirements of packing cement for export. In view of the large number of amendments, the Sectional Committee decided to bring out this fifth revision of the standard incorporating all these amendments so as to make it more convenient for the users. Further, following are the significant modifications incorporated in this revision: a) Requirement for insoluble residue has been specified as 5.0 percent, maximum irrespective of addition of performance improver(s) or otherwise. b) An upper limit of compressive strength at 28 days, equal to the minimum requirement plus 15 MPa, has been incorporated. c) SO3 content requirement has been revised to 3.5 percent maximum irrespective of C3A content, primarily to accommodate use of coal/pet coke as fuel which may have higher sulphur content; subject to the cement conforming to all the requirements of the standard. d) A clause has been introduced requiring manufacturer to furnish a certificate indicating alkali content if required by the purchaser. e) Requirement of marking of type and amount of performance improver(s) on the bag has been incorporated. f) Requirement of testing the cement samples at the earliest but not later than 3 months since the receipt of samples for testing, has been included. With the increase in SO3 content limit in this revision, suitable caution needs to be exercized for limiting the sulphates in concrete in accordance with the provision of IS 456 : 2000 ‘Code of practice for plain and reinforced concrete (fourth revision)’. Quantity of cement packed in bags and the tolerance requirements for the quantity of cement packed in bags shall be in accordance with the relevant provisions of the Standards of Weights and Measures (Packaged Commodities) Rules, 1977 and B-1.2 (see Annex B). Any modification in these rules in respect of tolerance on quantity of cement would apply automatically to this standard. This standard contains Sl No. (viii) of Table 2 and 12.2.1 which give option to the purchaser and Sl No. (v) of Table 3 and 9.2, 9.3, 9.4 and 9.4.3, which call for agreement between the purchaser and the supplier. The composition of the technical Committee responsible for the formulation of this standard is given in Annex C. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

No material shall be added after burning, other than gypsum (natural mineral or chemical, see Note), water, performance improver(s), and not more than a total of 1.0 percent of air-entraining agents or other agents including colouring agents, which have proved not to be harmful. This standard covers the manufacture and chemical and physical requirements of 33 grade ordinary Portland cement. 2 REFERENCES The standards given in Annex A contain provisions which, through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated in Annex A. NOTE — Chemical gypsum shall be added provided that the performance requirements of the final product as specified in this standard are met with. 4.1.1 Limit of addition of performance improver shall be as given in Table 1 and shall be inclusive of 1 percent additives as mentioned above. 3 TERMINOLOGY For the purpose of this standard, the definitions given in IS 4845 shall apply. If a combination of above performance improvers is added, the maximum limit of total addition shall be 5 percent. 4 MANUFACTURE 5 CHEMICAL REQUIREMENTS 4.1 Ordinary Portland cement, 33 grade shall be manufactured by intimately mixing together calcareous When tested in accordance with the methods given in Table 1 Performance Improvers (Clause 4.1.1) Sl No. Performance Improver Percentage Addition by Mass, Max Requirement (1) (2) (3) (4) i) ii) iii) iv) Fly ash Granulated slag Silica fume Limestone 5 5 5 5 v) Rice husk ash 5 vi) Metakaolin 5 Conforming to IS 3812 (Part 1) Conforming to IS 12089 Conforming to IS 15388 CaCO3 content calculated from CaO content shall not be less than 75 percent when tested in accordance with IS 1760 (Part 3) a) Reactive silica shall not be less than 80 percent when tested as per IS 3812 (Part 1) b) Pozzolanic activity index shall not be less than 90 percent when tested as per 10 of 1S 1727 c) Loss on ignition shall not be more than 5.0 percent when tested as per IS 1727 a) Silicon dioxide (SiO2) plus aluminium oxide (Al2O3) in percent by mass shall not be less than 94.0 percent when tested as per IS 1727 b) Loss on ignition shall not be more than 2.0 percent when tested as per IS 1727 c) Total alkalis as sodium oxide (as Na2O equivalent) in percent by mass shall not be more than 1.5 percent when tested as per IS 4032 d) Particles retained on 45 micron IS sieve (wet sieving) shall not be more than 1.5 percent when tested as per 1S 1727 1 IS 269 : 2013 6 PHYSICAL REQUIREMENTS IS 4032, ordinary Portland cement, 33 grade shall comply with the chemical requirements given in Table 2.

On large and important jobs where the concrete is likely to be exposed to humid atmosphere or wetting action, it is advisable that the aggregate be tested for alkali aggregate reaction. In the case of reactive aggregates, the use of cement with alkali content below 0.6 percent expressed as sodium oxide (Na2O), is recommended. Where, however, such cements are not available, use of alternative means may be resorted to for which a reference may be made to 8.2.5.4 of IS 456. If so desired by the purchaser, the manufacturer shall carry out test for alkali content.
